I have an older Zwave Schlage PIR Motion sensor which has worked fine on my HomeSeer system. I am converting everything over to HA, and was able to register the device just fine. Inside of HA, it shows up as a motion device, but it also shows as a switch as well. I am not sure why that happens. That being said, there are no motion alerts coming from the device. If I remove the cover, I get tampering alerts right away, so I know it is communicating. I’ve tried removing and adding the device to see if that would help and it hasn’t.
I’ve had a look in the ZwaveJS database, what is documented about this device’s, and is not a lot, it seems.
So maybe contact with the ZwaveJS devs could help somehow?
Post the device diagnostic file [1] and the debug logs [2] of your interaction with the device. You can remove the parts in the log that don’t refer to zwave_js.
The device config might need a setting to become a proper notification sensor instead of appearing as a light.
